Patented May 11, 1937 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to well covers and it has particular reference toa sanitary and safety cover for artesian and other wells.

The principal object of the invention is to provide an inexpensivearticle of manufacture designed to afford a sanitary and safety coverfor wells, whereby to minimize accidents and to prevent unsanitaryobjects from being thrown into a well.

Another object of the invention is to provide a cover of the characterspecified, capable of being produced in one piece so that a number ofthe articles can be packed and shipped in nested relationship or, in aplurality of sections calculated to reduce materially the size of theshipment. In

the latter case, assembling of the sections of the cover will requirebolts or rivets, easy to install, hence the problem of assembling is onewell within the skill of a person having ordinary mechanical knowledge.

With the foregoing objects as paramount, the invention has particularreference to its salient features of construction and arrangement ofparts, which will become manifest as the description proceeds, taken inconnection with the accompanying drawing, wherein:-

Figure 1 is a view of the invention in diametrical section as installed.

Figure 2 is a perspective view.

Figure 3 is a fragmentary, View of a modified form of the invention insections, and

Figure 4 is a plain view of a section, showing the means of attachmentthereto of a similar section, shown fragmentarily.

Continuing with a more detailed description of the drawing, reference isprimarily made to the preferred form of the invention shown in Figures 1and 2. In these figures, I designates the well in which there is shown aconventional type of pump 2 with depending tubing 3.

The invention is comprised of the metal stamping 4, embracing the tubing3, provided with a flared flange a and a belled top portion b forresistance against downward pressure.

The aperture through which is passed the tubing 3 is surrounded by aflange 0, produced by drawing the material of the cover. This flange istapped and threaded to receive the set screw 5 which bears against thepump tubing 3 to hold the cover against rotative displacement. It willbe understood however, that the flange c as shown, may be substituted bya removable flange and collar if such is found to be necessary ordesirable.

When the cover shown and described is set in place, it is desirable thata curbing B of concrete or other material be provided around theperiphery. This precaution will prevent infiltration of contaminatedsurface water into the well, as well as insuring against the fallinginto the well of small animals, insects etc., likely to contaminate thewater. Moreover, the curbing protects the surface shoulder of the welland prevents disintegration thereof.

In Figures 3 and 4 is shown a modified form of the invention.Substantially the same article as shown in Figures 1 and 2 is producedin the manner shown in Figures 3 and 4 in sections. As shown, thearticle is divided into four sections 1, cast preferably from light butsturdy material to provide flanges 11 disposed radially when thesections are assembled. These flanges are apertured to receive bolts 8adapted to hold the sections in assembled relationship.

It will also be observed that the sections 1 are so formed as to provideportions to complete the ferrule or collar 9 to embrace the pump tubingwhen the sections are assembled.

Manifestly, the construction shown is capable of considerablemodification and such modification as is considered within the scope andmeaning of the appended claim is also considered within the spirit andintent of the invention.

I claim:

As a new article of manufacture, a cover for wells and cisternscomprising the combination of a plurality of associated castings, eachconsisting of a segment of a circle having boundary flanges, the outerperipheral flange being disposed at an acute angle relative to the baseplane of said casting, the inner peripheral flange being disposed aboveand normal to said plane, and means for securing the radial flanges ofsaid sections together.
